I haven’t yet seen an in-depth interview with Villeneuve where he addresses whether or not he wants to continue making (admittedly thoughtful and overall excellent) adaptations vs original works.
Going back over his filmography, every film since Maelström (2000) (or perhaps Polytechnique in 2009) has been an adaptation of a previous work. I really love the work he does, and I would not want him to be tied down to existing properties. Then again, he may believe that adaptations are where he does his best work.
Whichever it is, let the man work the way he wants to work. I’m here for it.
